Subject: [PATCH v4,0/4] Cooperate with DSI RX devices to modify dsi funcs and delay mipi high to cooperate with panel sequence

From: Xinlei Lee <xinlei.lee@...iatek.com>

In upstream-v5.8, dsi_enable will operate panel_enable, but this
modification has been moved in v5.9. In order to ensure the timing of
dsi_power_on/off and the timing of pulling up/down the MIPI signal,
the modification of v5.9 is synchronized in this series of patches.

Changes since v3:
1. Rebase kernel-5.18-rc1.
2. Added dsi_enable protection.
3. Encapsulates the dsi_lane_ready function.

Changes since v2:
1. Rebase linux-next.

Changes since v1:
1. Dsi sequence marked with patch adjustment.
2. Fixes: mtk_dsi: Use the drm_panel_bridge.

Jitao Shi (3):
  drm/mediatek: Adjust the timing of mipi signal from LP00 to LP11
  drm/mediatek: Separate poweron/poweroff from enable/disable and define
    new funcs
  drm/mediatek: keep dsi as LP00 before dcs cmds transfer

Xinlei Lee (1):
  drm/mediatek: Add pull-down MIPI operation in mtk_dsi_poweroff
    function
